Alfagrog

Alfagrog is a porous foamed ceramic material, which is lightweight, strong and inert. It’s high surface area makes it the natural choice for colonisation by microorganisms in biological filtration systems resulting in cleaner water.

The Alfagrog range of porous ceramic filter media is made under controlled conditions in the UK. Selected clays and raw materials are rapidly sintered at high temperatures to produce a foamed ceramic porous mass, which is crushed and sieved to a convenient particle size. The manufacturing process ensures that no substances are present to adversely affect the health of fish or plants. The material is pH-neutral and can be used in both freshwater and marine applications.

Alfagrog is available in a wide range of sizes giving the end user optimum media surface area in varying water flow rates.

Why is it so effective?

The key to effective biological filtration is choosing media with the highest surface area possible to allow beneficial bacteria to colonise and remove waste from the water. Alfagrog has an extremely high surface area to volume ratio compared with other types of filter media on the market.

Alfagrog is made of a highly porous material that contains many thousands of tiny pockets in which bacteria can thrive, making it an ideal material for biological filters.

Warning: It is sharp on the hands when cleaning so please wear gloves
